In this article, the problem of determining pseudodynamic
pressure and its associatedforces on a rigid vertical retaining
wall is solved analytically using the horizontal slices method for
both reinforced and unreinforced walls. The use of this method in
conjunction with the suggested equations and unknowns offers a
pseudo-dynamic method that is then compared with the results of an
available software. In the proposed method, different seismic accelerations have been modeled at different soil structure heights. Reinforced soil pressure on a retaining wall and the angle of the critical failure wedge are calculated using the new formulation. It is shown that as the horizontal seismic acceleration coefficient increases the angle of the critical failure wedge is reduced and that the maximum extension
force can be increased for each layer by using stronger and longer
reinforcements. The results of the pseudo-dynamic method show that
both vertical and horizontal seismic accelerations are essential
coefficients for calculation of the required length and extension force
ofthe reinforcements and that their importance increases as the vertical
and horizontal seismic accelerations increase.. Also, the location of
the application point of the resultant pressure rises as the horizontal
seismic acceleration coefficient increases.
